Hello! I am Sam. I will teach you about Factoring Quadratics.
To Find the zero/roots/X-int by factoring: 1. Factor the quad and let it equal 0 (X - a) (X + b) =0 2. Set each factor = 0 (X - a) = 0 3. Solve for the variable in each factor. X = a, X = -b
This is how you do it.
Steps to solve by Square Roots 1. Isolate the exponent 2. Undo the exponent 3. Remember that you will need a plus and a minus sign when you take a square root I 4. Solve for the variable 5. Find the Approximate answers if necessary.
You can also solve Quadratics by Square Roots.
It's that easy, now you know how to solve quadratics by factoring.
